Online alarm clock for 3:16 am
Handing the Bluff wharf pickup to the next person at 3:16 am means leaving them a clear wake-up point, not a vague promise to get moving sometime before dawn. Set the alarm for the exact handover time so they can meet the fishing vessel without watching the clock through the night. There are 44 minutes until 4:00 am, enough for a final message about the berth, expected arrival, and who will be waiting.
Because the signal matters before anyone heads towards the wharf, test it now at a nearby time and listen for the actual sound. Check that the volume is noticeable in the room where the person will rest, then return the setting to 3:16 am. A browser alarm cannot alert them after its page is closed or their phone or laptop goes to sleep, which could leave the fishing vessel arriving with nobody ready at the wharf.
For a middle-of-the-night handover in Bluff, keep the instructions beside the alarm short enough to understand while still groggy: vessel name, berth, warm layers, keys, and departure time. Allow some breathing room after the pickup as well. If another task is due later that day, record its time separately rather than relying on memory after an early start, and leave a realistic gap for tying up, unloading, and getting back from the harbour.
